The 1958 Chevrolet Impala Convertible represents a pivotal moment in American automotive design, marking the birth of a legendary nameplate. This specific example, finished in the eye-catching Cay Coral, showcases the unique one-year-only styling that collectors highly prize today. It departs from the previous year’s vertical look for a longer, lower, and wider stance that defined the late fifties. Beyond the striking paint, this vehicle balances original character with thoughtful mechanical upgrades for better drivability. Seeing this car in person reveals why the 1958 model remains a standout at any high-profile auction. It serves as a rolling sculpture of chrome, fins, and mid-century optimism.
Upgraded 348 V-8 Engine and Drivetrain
Power for this 1958 Chevrolet Impala Convertible comes from a rebuilt original 348 CI V-8 engine. While the engine block maintains its vintage pedigree, a modern Edelbrock FiTech fuel injection system manages the fuel delivery. An aluminum intake and PerTronix distributor further enhance reliability during long summer cruises. The power moves through a heavy-duty Turbo 350 automatic transmission, providing smoother shifts than the original factory units. A four-core aluminum radiator keeps the big-block cool even when idling in parade traffic. This combination of classic displacement and modern technology creates a very dependable and powerful driving experience.
Chassis Modernization and Handling Features
Driving a full-size classic requires confidence, which is why this 1958 Chevrolet Impala Convertible features several chassis improvements. Front disc brakes replace the original drums to provide significantly more consistent stopping power. Power steering makes navigating tight corners or parking lot maneuvers effortless for the driver. The car sits on iconic Tru-spoke wire wheels that add a premium flair to the overall silhouette. A stock 3.08 rear gear ratio ensures the car remains comfortable at highway speeds without high engine revolutions. These updates allow the owner to enjoy the car on modern roads without the stress typical of older drum-brake systems.
Interior Luxury and Period Accessories
The cabin stays true to its roots with a striking Coral, White, and Gray tri-color interior. Notably, the seats still wear clear plastic covers, a nostalgic touch that preserved the upholstery over the decades. Dakota Digital gauges are neatly integrated into the dashboard to provide the driver with precise engine data. An Autosound AM/FM radio offers modern audio connectivity while maintaining a factory-style appearance in the center stack. The white power-operated convertible top features a brand-new motor for seamless operation during changing weather conditions. Every detail, from the factory-tinted glass to the Continental kit, reflects a high level of care.
Power and Performance Specifications
The 348 CI V-8 engine provides the substantial torque necessary to move this heavy cruiser with authority. Its FiTech electronic fuel injection ensures crisp throttle response and easier cold starts compared to a traditional carburetor. An American Classic generator and alternator setup provides ample electrical power for the digital upgrades and lighting. The inclusion of an original GM Continental kit adds significant length and visual prestige to the rear profile. Sturdy front disc brakes ensure that all this momentum can be brought to a halt safely and quickly. These specifications make the Impala a formidable performer among its peers at the Glendale event.
Summary of the Cay Coral Classic
